既述の通りである。 Next, the operation of this embodiment will be explained. First, to explain the operation of the appliance, in the water system, water is supplied to the hot water flow controller 1.
The hot water is heated by the heat exchanger 2, turned into hot water, and discharged from a faucet (not shown). Near the outlet of the heat exchanger, the temperature of the water is detected by a thermistor 3, and the opening degree of the proportional valve 7 in the gas system is adjusted based on the signal. In the gas system, the starter is lit by opening the main valve. In this state, when a faucet (not shown) of the water system is opened and a water flow is generated in the water system, the bench lily pipe 13 acts, the internal pressure of the low pressure chamber 15 becomes lower than the internal pressure of the high pressure chamber 14, and the diaphragm 16 is moved by the spring 17. The governor valve 10 regulates the flow rate due to fluctuations in water pressure, and the micro switch 18
Turn on and open the hydraulic valve 6 of the gas system.
After a while, the gas is supplied to the burner 8 via the proportional valve 7, and is ignited by the pilot flame 5 to heat the heat exchanger 2. The operation of the proportional valve 7 is as described above.

て、湯量が例えば、12／分、10／分、８／
分、６／分と自動的に制御される。 The operation of water flow control will be explained. The water that enters through the inlet 9 passes through the governor valve 10 and finally has its flow rate determined by the piston valve 12. Therefore, if the degree of opening of the piston valve 12 can be changed in conjunction with the notch position of the rotary switch 35, the amount of hot water when the faucet is fully open can be automatically controlled by the hot water temperature setting operation. For example, if you set the rotary switch 35 to the notch 3, the water temperature will change at the temperature setting resistors 29 and 3.
The water temperature is determined at 0 (characteristics of notch 3 in Figure 1). At the same time, the current flowing through the electromagnetic coil 19 reaches a current value regulated by the hot water amount setting resistor 34. Therefore, the opening degree of the piston valve 12 at this time is the point where the electromagnetic force due to this current and the reaction force of the spring 20 are balanced, that is, point B in Figure 5, and the amount of hot water at this time is as shown in Figure 6. , 8/min. In other words, by simply switching the rotary switch 35, the hot water amount can be changed to 12/min, 10/min, 8/min, etc. corresponding to the notches 1, 2, 3, and 4.
automatically controlled at 6/min.

る。 As explained above, according to the present invention, even if the faucet is fully opened, the amount of water flowing can be automatically controlled according to the hot water temperature setting, so the amount of hot water corresponding to the hot water temperature setting can always be automatically obtained. Compared to the conventional complicated operation of manually adjusting the opening degree of the faucet and setting the water temperature, it is extremely simple and user-friendly as all you have to do is set the water temperature. You can maximize your performance.
